A: Using F100 Configuration
Configuring NTP & SNMP Parameters
F100 CONFIG instructs the XL-GPS unit to transfer its NTP and SNMP configuration files to an FTP
server so the user can edit them. When finished editing, the user transfers the config files back to the
XL-GPS using the F100 CONFIG command.
Overview of Steps
Set up an FTP server on your workstation.
Using the XL-GPS’s command line interface, enter the F100 CONFIG get command. The XL-
GPS transfers copies of its configuration files over the network to the FTP on your PC.
Edit the configuration files.
Give the XL-GPS a new command, F100 CONFIG set. The XL-GPS retrieves copies of the
edited configuration files from the FTP and overwrites it’s current config files with the newly edited
ones.
Set up the FTP Server
To save time and trouble, download a pre-configured FTP server from http://www.ntp-systems.com/zip/
warftpd1.zip and extract it to the C:\ drive on your workstation. Otherwise, customize your existing FTP
server setup as described in this section.
When performing these operations, the user issues command line instructions to the XL-GPS. The XL-
GPS responds to those commands by connecting to the FTP server and transferring files to and from the
FTP. The XL-GPS gives the FTP server ‘Anonymous’ as its user name, and uses a null password (e.g.,
the equivalent of pressing the Enter key on your keyboard instead of entering text). The FTP server must
be configured as follows:
Anonymous log-ins are enabled
The password for Anonymous is disabled, or allows a null password
Anonymous has read/write privileges to Anonymous’s home directory.
Get the IP Address of the FTP Server/Workstation
If the FTP server is running on your Windows workstation, open a DOS command line window on the
workstation:
•Click Start, Run, and type cmd, or
•Click Start, Programs, (and Accessories in some cases), and select Command prompt or DOS
prompt.
At the command line, type ipconfig
Make note of the IP Address.
